5.75 is the answer.
If you subtract 43.9 FROM 49.65, that's what you get.

Consider the given matrix. 1 −1 0 5 1 4 0 1 1 Find the eigenvalues. (Enter your answers as a comma-separated list.) λ = Find the

fomenos

Answer:

Step-by-step explanation:

We have to diagonalize the matrix

$\left[\begin{array}{ccc}1&-1&0\\5&1&4\\0&1&1\end{array}\right]$

we have to solve the expression

$|A-\lambda I|=0$

Thus, by applying the determinant we obtain the polynomial

$(1-\lambda )^3+5-4=0\\(1-\lambda )^3+1=0\\$

$-\lambda^3+3\lambda^2-4\lambda+2$

$\lambda_1=1\\\lambda_2=1-i\\\lambda_3=1+i\\$

and the eigenvector will be

$v_1=(-4,0,5)\\v_2=(-1,-i,-1)\\v_3=(-1,i,1)$

Answer:

B. Subtract 7

Step-by-step explanation:

You always want to isolate the x term to solve for x in any equation. Therefore, we need to move the 7 to the other side. Only way to do that is to subtract 7 on both sides.

Hi there,

I’m attaching the same image with more information on the graph.

The 4th mark (the middle dashed line) is marking the mean (70).

The 3rd and the 5th are marking the mean less/plus 1 deviation.

So, 70.5 is the 5th mark.

Taking this into account:

The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%

The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%

Good Luck!
